根因: UIManager._btnLimbFixation/_btnSplintFixation调用SwitchFixation 与PageController的OnFixationSelected双重触发,StepManager._mode被设为Learn 导致OnStepInteractionComplete→NextStep→WomanStepNext自动跳过步骤。 修复: 1. UIManager.BindButtons移除_btnLimbFixation/_btnSplintFixation的SwitchFixation绑定 2. ExperimentFlowCoordinator.OnAnywhereClicked增加无Config步骤时忽略的注释守卫
